Question
When benzene undergoes a Birch reduction, the resulting product is
Solution
When benzene undergoes a Birch reduction, the resulting product is 1,4-cyclohexadiene.
Here's a step-by-step explanation:
-
The Birch reduction is a type of organic reaction where an aromatic ring is partially reduced under extremely basic conditions.
-
In this reaction, benzene, which is an aromatic compound with a ring of six carbon atoms, is treated with a mixture of ammonia, sodium, and an alcohol, typically ethanol or tert-butanol.
-
The sodium donates an electron to the benzene ring, which breaks the aromaticity and forms a radical anion.
-
This radical anion then reacts with an alcohol molecule, which donates a proton to one of the carbon atoms.
-
The sodium donates another electron to the radical anion, which then reacts with another alcohol molecule to donate a proton to a carbon atom on the opposite side of the ring.
-
The end result of this reaction is 1,4-cyclohexadiene, a compound with a six-carbon ring and two double bonds.
